Evaluates the closed-cycle magnetohydrodynamic (MHD) system of electric power generation in the overall context of the pacing technologies and estimated costs, with emphasis on fossil fuel. A number of problems unique to the closed-cycle configuration are discussed. Cost estimates as presented in the Energy Conversion Alternatives Study (ECAS) are used to compare (1) other advanced systems with MHD, (2) open- and closed-cycle MHD, and (3) the closed-cycle estimates of General Electric and Westinghouse. Closed-cycle MHD, despite its many problems, remains an intriguing concept of electric power generation that should not be ruled out at this time. 85 pp. Bibliog.
